We have 2 Tivo 6 boxes - first one and the the other lost the capability of connecting to the Virgin Media service, so whilst we can receive tv channels, we cannot see the schedule or gain access to apps. Any advice?
If the channels are working, which this comes from the cable connection, but apps and guide isn't working, this might be due to the box's connection to the hub which you stated was a wireless connection. Are you able to switch to a wired connection? Or any of the suggestions from @japitts helped?
